To a'lwhom-it may concern# -V Be it known that we, WALTER GJ'ELZE and F:'SoHUMANNycitizens of the l 'United States,. and=residents of 'Woodhaven 6 and Baltimore, respectively,inrthe counties of Queens and Baltimore, respectively,I and States'of. New .Yer-lr and' Maryland, respec- `l `Impr'oven'lents iin Heatersifor Metal Tires, 10 (yf-which the following is a-specication.

Tle'invention relatesto a metal" tire 'heater, and 4more particularly to a heater designed for use in connection with the eX pansionof metalltires suchr ask are' employed on locomotives, wagons and the like llt has for itsobject a heater ofthis'eharacte'r which may readilyl be applied to the Atirefto be heated without necessitating re- 'moval, in the case, for example, of 'a locomotive or like apparatus, of aportionvof the' driving gear' thereof- Y The heater,simi larly,-may readily be removed aftercompletion'ofthe heatlng operationgand thefin- L 'vention has fora further object-a novel con- 'struction of heater whereby ,suiiicient `adjustabil-it'yvis ,attainedg to t, within limits,

the heater to diere'ntdia-meters inl .orde-r tocornpensate'ior wear of the tires. .A still furtherfobject of' theY invention `l resides in the arrangement for securing'equal spacing ery'of the tire to'belfieatedl in -orde'rlt'o insure' a .uniiorm heating o'f thelatter, the 'particular arrangement insuring, also, .a more equaldistrilmt-io'ny of the. gasified ifnel mixture `to'theheat'er. l

' The'natnre' of the inventiom-however, will best be understood when describedin-connection" with1 the' accon'ipanyingl .l drawings, inwh'ich--e y `1 Fig.. 1- isV a front elevation partlyfin section, :ofi the" n'ovelj` heater member applied 'to a tire of a' locomotive, las one application yof' theinvention. f

su'chheatersfofone or more tubnlarfm'em- "i Ibersin'the form fof la' circle zof fixedv diameter and adapted to 'be located over the-pe 'riphery of Vthetireto beheated. lnfthe present instance, -fhow`ever,` the heaterv is constructed; in'manner to'allow of Ia' separation 'i thereof, for example, it maybe composed of `two semi-circular tubes-'or half:sectionsy 11 andilQ having their 'respective ends-13 and 14 sealed so that the tubesare'independent' of each other so aras the supplyingrof vfuel -"i:

is concerned. The invention,

the Y two ends if are arranged toy be .f 'suitably drawn together, for example fas 'indiated and where ytwo halvesfare employed,y thru lugs l5 and: 16 extending outwardly at right angles from the v respective L sealedav ends i3 and 145; 'The' lugs are drilled, also, to allow 'bolts or stay 'rods 17` land '18V` respectively :to pass thru the cooperating pairsv of 4 lugs 15',

In ybeing y ble '-mixture obliged to ftravel in opposite directions thruthe sections-#11V andglf and is arranged to he. deliveredtherefrom,more orless equally, thrula'series of radraliopen- A ings 26 inthe under face kof said sections. The flames, upon ignition of the fuel, will thenl be directed radially toward the surface of the tire l0 ina series of jets substantially I circumscribing the said surface; and in thus dividing the stream ofthe combustile Vmixture, the intensity thereof is substantially the same over the entire surface.

In order further to insure that vthe vintensity of the heatingeffect on thel surface of the tire shall bey .substantially equal thruout, there are provided on the Vtwo half sections Il and 12 a plurality .of inwardly extending cylindricallugs or projections 27 which are spaced at equal lintervalsand aredesigned; to contact with ,the tire surface as the two halves are drawn together.Y In this 'v manner, the tubular sections are bent over lso iuiiformlyand their opeiiings26 are all displaced substantially the same distancefrom the tire` surface, the desired spaced relationship effected thereby being maintained tliruout the heating period by the locking arrangement` provided at the lends of the two semi-circular sections comprising the heater.; Y t Y In applying'the heater to the tire, the two sections'll and l2 `are separated'the required extent, and which usually necessitates dismantling o-f the header at the union g 25,-fand are then laid over the surface of a tire 10, the lugs 26 being directed thereto and .more or less in contact with said surxface. Thereupon, the two pairs of ends 13,

' lt'are secured tofeach other and the sections tightened up overthe rim by means of 4the rods 17, 18and nuts 19, 2O until all'of the'lugs 27` contact with the tire'periphery. The combustible mixture may then vbe introduced t-hruthe header, dividing into two streams, and ignited at the outlets 2G to provide anannulus of flame jets about the tire. When sufficiently heated, the tire may beseparated from its set forth.`

We claim l. A tire heater consisting of a hollow annular member comprising twoindependent heaterv as hereinbefore andseparable tubular Vportions lying in a common plane and sealed at their ends, each portion being provided with connections for a gaseous combustible mixture and having a series of radially directed outlets along the inner surface, and means to draw the portions together.
